A system for protecting a sector of tissue from exposure to surgically directed radiation includes a processor and an input device, a camera, and an output screen in electronic communication with the processor. A software resident on the processor receives camera data containing an image of a region
A system for protecting a sector of tissue from exposure to surgically directed radiation includes a processor and an input device, a camera, and an output screen in electronic communication with the processor. A software resident on the processor receives camera data containing an image of a region of tissue, which includes at least a portion of a predetermined area desired to receive therapeutic radiation. The software also routes the image for display superimposes thereon first indicia indicative of the predetermined area. Data are received on a location of a sector of the tissue desired to be protected from the radiation and for superimposing on the displayed image second indicia indicative of the sector. In a specific embodiment the tissue is an eye and the predetermined area is at least a portion of the cornea.

A system for protecting a sector of tissue from exposure to surgically directed radiation includes a processor and an input device, a camera, and an output screen in electronic communication with the processor. A software resident on the processor receives camera data containing an image of a region of tissue, which includes at least a portion of a predetermined area desired to receive therapeutic radiation. The software also routes the image for display superimposes thereon first indicia indicative of the predetermined area. Data are received on a location of a sector of the tissue desired to be protected from the radiation and for superimposing on the displayed image second indicia indicative of the sector. In a specific embodiment the tissue is an eye and the predetermined area is at least a portion of the cornea. a cam that is configured to be coupled at a distal end to the needle, and coupled at a proximal end to the medical instrument, the cam including at least one helical slot provided at the distal end thereof; a collar that is configured to ride along the at least one helical slot so that the collar moves in a linear direction on the cam; and a control link that is coupled to the collar and that is configured to move the collar in the linear direction, wherein, when the control link is actuated, the collar is moved in the linear direction, thereby causing the cam and the needle to rotate to thereby cause the needle to spin between seed implant positions. 2. The apparatus according to claim 1, wherein the needle rotates at least 90 degrees between seed implantation positions. 3. A method for depositing seeds into a patient for treatment of patient, by way of a needle that is coupled to a medical instrument, the method comprising the steps of: inserting at least one seed into a first position with a patient's body, by way of the needle; moving the medical instrument away from the patient to thereby move the needle to a second position within the patient's body; simultaneously with the moving step, spinning the needle between the first position and the second position, wherein the spinning step helps maintain at least one seed at the first position within the patient's body, wherein the medical instrument is moved by a user operating a control on the medical instrument to cause the medical instrument to automatically move from the first position to the second position. 4. An apparatus for depositing at least one seed at predetermined locations within a patient's body, comprising: a cam that is configured to be coupled to both an end of the medical instrument and an end of a needle, the cam including at least one helical slot; a collar that is configured to ride along the at least one helical slot so that the collar moves in a linear direction on the cam; wherein, when the collar is moved in the linear direction, the cam and the needle rotate to thereby cause the needle to spin between deposit locations. 5. An apparatus for depositing at least one seed at predetermined locations within a patient's body, comprising: a means for coupling a needle to a medical instrument; a means for sliding configured to ride along said means for coupling the needle to the medical instrument so that the means for sliding moves in a linear direction; and a means for actuating that is configured to move said means for sliding in the linear direction, wherein, when the means for actuating is actuated, the means for sliding is moved in the linear direction, thereby causing the means for coupling and the needle to rotate to thereby cause the needle to spin between deposit locations. 6. The apparatus according to claim 5, wherein said means for coupling the needle to the medical instrument comprises a cam that is configured to be coupled to the needle and the medical instrument, the cam including at least one helical slot provided at the distal end thereof. 7. The apparatus according to claim 6, wherein said means for sliding comprises a collar that is configured to ride along the at least one helical slot so that the collar moves in a linear direction on the cam. 8. The apparatus according to claim 7, wherein said means for actuating comprises a control link that is coupled to the collar and that is configured to move the collar in the linear direction, wherein, when the control link is actuated, the collar is moved in the linear direction, thereby causing the cam and the needle to rotate to thereby cause the needle to spin between deposit locations. -4827914, 19890500, Kamazawa, 601/101; US-5716332, 19980200, Noble, 601/108; US-5951501, 19990900, Griner, 601/108
